The optional default value is used to implement `ConfigUserPath::Reset()`. Since `ConfigUserPath` must not be empty, there was no easy way to reset these paths to their default value. With this change users of `ConfigUserPath` can now set the default path. At the moment users of `ConfigUserPath` must place a reset button and connect a callback to `ConfigUserPath::Reset` on their own.
